Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchange device using two types of liquids.

As shown in Fig. 1, in conventional heat exchange devices, when heat is transferred from the high temperature fluid A side to the low temperature fluid B side, there is a thermal resistance due to the presence of the partition wall C between the two, so the temperature inevitably increases. will decrease.

Therefore, even if there is a large amount of heat flow, the temperature is low, making it difficult to generate steam, for example.

The present invention was made in consideration of the above points, and eliminates the temperature drop by removing the partition wall in the conventional heat exchange device, thereby making it possible to perform efficient heat exchange.

This invention will be explained below.

FIG. 2 shows an embodiment of the present invention, in which 1 is a container, and an inlet 2 and an outlet 3 for high-boiling liquid Lh are provided above and below the container.

Further, an introduction pipe 4 for a low boiling point liquid Ll is attached to approximately the center of the container 1.

A large number of spout ports 5 are formed in the introduction pipe 4, from which the low boiling point liquid L1 is spouted into the high boiling point liquid Lh.

A steam outlet 6 is formed at the top of the container 1.

Reference numeral 7 denotes a high-boiling point liquid separation trap, which is made of a mesh and prevents the high-boiling point liquid Lh from flowing out together with the vapor Lg from the vapor outlet 6.

Note that 8 is an object made of a porous or inorganic material having bubble generation nuclei, and is provided to promote vaporization of water Le.

In order to simplify the explanation, the operation of the embodiment shown in FIG. 2 will be described below using silicone oil as the high boiling point liquid Lh and water as the low boiling point liquid L1.

It is assumed that high-temperature silicone oil Lh enters through the inlet 2, exits through the inlet 3, is heated again, and returns to the inlet 2.

Therefore, the container 1 is always filled with high temperature silicone oil Lh as shown in the figure.

On the other hand, the low temperature water L1 from the introduction pipe 4 is ejected from the ejection port 5.

In this case, the density of the silicone oil Lh is smaller than that of the water L1, so the water Ll rises in the silicone oil Lh, and during that time, sufficient heat exchange takes place and it becomes steam, which is then released from the steam outlet 6 as steam Lg. taken out.

As a result of this operation being performed continuously, the water Ll turns into steam Lg one after another and exits the steam outlet 6.

FIG. 3 shows another embodiment of the present invention, in which an inlet 2 for silicone oil Lh and an inlet pipe 4 for water L1 are provided below the container 1, and an outlet 3 is provided above the tile.

Reference numeral 8 denotes an object made of a porous or inorganic material having a bubble generation nucleus, and is provided to promote the vaporization of the water Ll.

Next, the effect will be explained.

Silicone oil Lh enters the container 1 through the inlet 2 and exits through the outlet 3.

On the other hand, the water Ll is ejected from the ejection port 5 formed at the end of the introduction pipe 4, contacts the silicone oil Lh, and receives heat.

In this case, since the silicone oil Lh and the water L1 are both liquids, all of them are not vaporized due to liquid-to-liquid contact, and some of them do not boil easily.

This is because contact between the silicone oil Lh and the water L1 alone does not create a foaming nucleus, that is, a trigger for boiling.

However, in this example, since there is an object 8 having a bubble generation nucleus, when the water L1 collides with the side wall of the object 8 while traveling through the silicone oil Lh, it is given an opportunity to boil, and therefore vaporization is promoted. Ru.

Note that the object 8 may be anything that can cause the water Ll to boil; for example, it may be filled with a ball, etc.
Silicone oil Lh and water L1 may be passed between them.

The embodiments shown in FIGS. 2 and 3 are heat exchange apparatuses for generating steam, while the embodiment shown in FIG. 4 is an embodiment of the heat exchange apparatus as a cooler.

In this embodiment, an inlet 12 and an outlet 13 for the low freezing point liquid L'h are provided in the center and lower part of the container 11, while an inlet pipe 14 for the gas L'g of the high freezing point liquid L'1 is connected to the bottom of the container 11. Further, it is attached at the bottom, and a cooling liquid outlet 16 is provided at the top.

In addition, 15 is a spout.

In this case, the low freezing point liquid density is set higher than the high freezing point liquid density.

The following explanation uses silicone oil as a low freezing point liquid.
Water will be used as the high freezing point liquid L'l and steam will be used as the gas L'g.

Now, the steam L'g is introduced into the inlet pipe 14 at a low temperature, for example -
When ejected into the silicone oil L'h at 40°C, the steam L/g comes into sufficient contact with the silicone oil L'h, imparts heat to the silicone oil L'h, liquefies it, and becomes water L'l as a cooling liquid. It is taken out from the take-out port 16.

Steam L'g is replenished one after another, and silicone oil L'
Since low temperature water is also replenished one after another, water L'l that is continuously cooled can be obtained from the cooling liquid outlet 16.

Even in the case of the embodiment shown in FIG. 4, steam can be obtained from the cooling liquid outlet 16 by using the method shown in FIG. This is easy to understand.

That is, the device of the present invention is a heat exchange device that can be applied to both steam generation and cooling water generation.

In that case, a condensation nucleus generating material is provided as shown in 17 in the same figure,
All you have to do is promote condensation.

In addition, although two types of liquids are used in each of the above examples,
It is clear from the embodiment shown in FIG. 4 that it is not necessarily used as a liquid, but may be heated and turned into a gas.

Furthermore, in the above embodiment, the density of the high boiling point liquid Lh was higher than the density of the low boiling point liquid L1, and the density of the low freezing point liquid L'h was higher than the density of the high freezing point liquid L'h. These may have an opposite relationship.

However, in that case, it is necessary to appropriately determine the positions of the inlet and outlet of each liquid.

As explained in detail above, in this invention, heat exchange is performed by bringing two liquids that do not melt into each other and have different densities into direct contact with each other. Unlike conventional systems, there is no reduction in efficiency due to thermal resistance caused by partition walls, and heat exchange can be performed with extremely high efficiency.

Furthermore, this invention circulates one of the liquids within the container;
Since the other liquid is ejected into it, both liquids come into direct contact and efficient heat conversion is performed, and it can also be used as a device for generating gas such as steam or as a cooling device. has advantages.
